# Some CMake targets (not known at the moment of processing) could be set to |
|
# compile for multiple architectures as specified by the OSX_ARCHITECTURES |
|
# property, which is target-specific. We should neither inspect nor rely on |
|
# any CMake property or variable to detect an architecture, in particular: |
|
# |
|
# - CMAKE_OSX_ARCHITECTURES |
|
# is just an initial value for OSX_ARCHITECTURES; set too early. |
|
# |
|
# - OSX_ARCHITECTURES |
|
# is a per-target property; targets could be defined later, and their |
|
# properties could be modified any time later. |

# |
|
# - CMAKE_SYSTEM_PROCESSOR |
|
# does not reflect multiple architectures at all. |

# |
|
# When compiling for multiple architectures, a build system can invoke a |
|
# compiler either |

# |

# - once: a single command line for multiple architectures (Ninja build) |
|
# - twice: two command lines per each architecture (Xcode build system) |

|
# like XCODE_ATTRIBUTE_OTHER_CPLUSPLUSFLAGS[arch=arm64] or similar. |

# the compiler to dispatch arch-specific arguments to a designated backend. |
